To all whom it may concern: A

Be it known that I, PETER PInNrii, a citizen of Poland, and resident of Linfield, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Collapsible Bookstands, of which the following 1s a specification.

This invention relates to bookstands or bookcases, and has for its main object to provide a neat and compact collapsible bookstand which may readily be folded into a small parcel for transportation.

The above and other objects will become apparent in the description below, in which characters of reference refer to likenamed parts in the drawings.

Referring brieiy to the drawings, Flgure 1 is a front elevational View of my bookstand in extended position.

Fig. 2 is a side elevational view of the same.

Fig. 3 is an enlarged view in perspective of one of the detachable doors, showing the means for releasably securing the same to the body of the stand.

Fig. 4 is a front elevational View of the bookstand in partly collapsed position.

Fig. 5 is a perspective view of the same in completely collapsed position.

Referring now in detail to the drawings, the numeral 1 indicates the base of the stand, supported upon feet 2. The base 1 is continued upward as the lowerframe 4to which is attached by hinges 5 the upper frame 3. The upper side walls are composed of collapsible membersl 6 and 7, mutualy connected by hinges 8, and the latter hinge 1y attached to the side walls of the lower frame 4. The frame 4 extends also across the front of the lower member in the form of a ledge 4, the latter, together with the base 1 and the side walls of the frame 4, inclosing a rectangular opening in which are mounted collapsible doors in the following manner. A door 15 is hingedly attached to one side wall of the frame 4 by hinges 16, and another door 17 is hingedly attachedto the other side wall of the frame 4 by hinges 18. A third door is hingedly attached, by hinges 20, to the latter door. Thus, as shown, three doors of equal size cover the inclosure above-mentioned, and said doors are generally constructed of wood or metal frames and glass panels.

In the upper frame 3 a door 21 is provided with detachable hinges 22 by'means of which the door 21 may be attached to or removed from the side walls Gand 7 when the latter are in extended position. `For this purpose a pin 28 is fixed in each of the parts 6 and 7, and the hinge 22, which is fast to the door 21, :is provided with a keyhole slot 27. In slipping the latter over the pin 28, the circular part is first passed over said pin, and then the hinge is lowered until the pin rests snug against the shoulder 27, thus assuring a secure retention of the hinge by the pin. Another door is similarly attached to the other collapsible side walls 9 and 10, by means of hinges 26. A middle door 23 is attached by hinges 24 to the door 21. Thus again are provided three equally sized doors to cover the upper front opening of the case. In order to obtain access to the books in the upper portion of the stand, the latter doors may be opened; and in order to obtain access to the books in the lower portion ot the stand, the doors 15, 17, and 19 may be opened.

I have provided an ornamental cornice for the stand which I have indicated at 12.y and the same may be attached to the top of the stand by means of spring clips 13 and a brace 14; this cornice is attached before the doors 21, 23, 25, by slipping the said brace and spring clips about the top panel of the frame 3.

Means for retaining the collapsible walls 6 and 7 in their extended position are indi cated in Figs. l, 2, and 4. These comprise a tongue 30 hingedly attached to the top panel of the frame 3, and having a vertical slot therein at 31 for the passage therethrough of a latch 35 fast to the upper wall 7. By inserting a small pin or other means through said latch when in the positions shown in Figs. 1 and 2. the walls 6-7 will readily retain their vertical position. Similar means, not shown, may be provided ou the other walls 9 and 10.

Assuming, now, that the bookstand is in the fully extended position shown in Figs. 1 and 2, and it is desired to collapse the same into the small volume shown in Fig. 5, the doors 21, 23, and 25 are first removed in the manner which is obvious; these doors are then laid in the bottom of the stand as shown in dotted lines in Fig. 4. Then the side Walls 6 7, and 9-10, are collapsed as shown in Fig. 4, resting in the position shown, for example, by the walls 9 and 10, in said figure. Thereafter the cornice 12 is detached from the top panel of the frame 3, and the same is inserted into the bottom of the stand, resting upon the doors 21, 23, and 25, and upon the Walls 6-7 and 9--10; for clearness, this cornice has been omitted from Fig. 4, but its being so disposed of is readily obvious. The doors 15, 17, and 19 are then all closed. Finally, the upper frame 3 is swung .about its hinges 5 over the bottom frame 4, into the position shown in Fig. 5. In order to provide safe locking means for the stand, a latch 32 is `fixed to the lower frame side wall and the slotted tongue 30, which is hingedly attached to the frame 3, engages said latch, through which a pin may be passed in order to prevent the escape of said tongue and thus to lock the device in collapsed position.

The sequencey of steps in extending the stand is, of course, in the reverse order of that described above for collapsing the same.

I claim:

1. A collapsible bookstand comprising a base, a lower frame mounted upon said base,

an upper frame hingedly mounted upon said lower frame, rigid side walls on said lower frame, collapsible side walls hingedly attached to said rigid side walls comprising a plurality of folding members, means for retaining said collapsible side walls in secure extended position; doors for the front of said upper frame, detachable hinges for mounting said doors in said upper frame, and doors in said lower frame.

2. A collapsible bookstand comprising a base, a lower frame mounted upon said base, an upper frame hingedly mounted upon said lower frame, rigid side walls on said lower frame, collapsible side walls hingedly attached to said rigid side walls comprising a plurality of folding members, means for red taining said collapsible side walls in secure position, doors for the front of said upper frame, detachable hinges for mounting said doors in said upper frame having key-hole slots therein, pins on said collapsible side walls adapted to engage said slots, and doors in said lower frame.

Signed at Linfield, in the county of Montgomery and State of Penna., this 14th day of February, A. D. 1920.
